Extract Just A Single Digit Character From A String?

Oct 31, 2010

I am trying to extract just a single digit character from a string.

my string is 'constructions-01_0'

I want to extract the very last character, the 0.

how do I do this?

Should I use String.match() or String.split() methods or is there another method I shoud use?

And what should the regExp be to get that last digit?

also separately I want to get the double digit and put that into another string, the 01.

How do I extract just that bit?

ChangeYear - GetFullYear - SetFullYear Functions - Extract The 4-digit Value From The Today Variable And Store The Value In A Variable Named Year

Oct 13, 2009

a.) specify two parameters for the changeYear function: today and holiday.

function changeYear(today)(holiday){

b.) in the first line of the above function, use the getFullYear() date method to extract the 4-digit value from the today variable and store the value in a variable named year.

first line

c.) in the second line; use the setFullYear() date method to set the full year of the holiday date object to the value of the year variable.

second line

d.) in the third line, use a conditional operator on the year variable. The test condition is whether the value of the holiday date object is less than the today date object. If it is, this means that the event has already passed in the current year and the value of the year variable should be increased by 1.

third line

e.) in the fourth line of the function, again set the full year value of the holiday date object to the value of the year variable.

Get The Last Character Of String?

Feb 4, 2011

I had a difficult time figuring out how to get or test the last character of a string with javascript.

I found plenty of removing the last character, but not for just checking what the last character of a string is using javascript.

// create string
var str = new String("No Periods Allowed.");
// alternatively get string from field:
// var str = document.getElementById('textbox').value;

[Code]....

Well, finding that easily on a search would have saved me some time.

Invalid Character In String Reference

Jul 23, 2005

Is there anything 'wrong' with setting the value of a drop down menu
using the following?

document.frmStep1.drpInvaddress.value = 'A1020761603!>>R2'

This string is a key in our database that I have no control over and I
want to set the value of the menu according to this value because it
is unique. I suspect that the '' or the '>' or the '!' is making
Javascript think that this is a different type of data than string.

Is there a way to 'force' Javascript to interpret this as string?

Newline Character In String Constant

Jul 23, 2005

I have a form with a textarea field. I want to validate the input from
the textarea using javascript. Suppose I want to check that the user
has not entered the string:
"Hello
World!"

To do this I am using the script:
form["text"].value == "Hello
World"

But this gives an "unterminated string constant error" because the
browser converts this to:
form["text"].value == "Hello
World"

So how do I do my check?
